..This selective review provides an outline and synthesis of studies that assess the neurotoxic mechanisms of methamphetamine, as well as those that evaluate the cognitive sequelae of methamphetamine abuse...

..1990). All subjects (10 controls and 9 paranoid schizophrenia patients) were studied with FDG-PET while performing a computerized trial-by-trial version of the Stroop task during the uptake phase of the tracer (Carter et al. 1992)...

..As psychostimulants such as methamphetamine (MA) are particularly neurotoxic to the dopaminergic system it was of interest to examine the performance of MA-dependent individuals on a task of spatial attention...

Functional connectivity and working memory in schizophrenia: an EEG study

..The goal of the present study was to extend our previous findings on long-term methamphetamine (MA) use and drug abstinence on brain metabolite levels in an expanded group of MA-dependent individuals...

..The current findings also suggest that when a course of action is not implied by an irrelevant feature, outpatients' behavior is not modulated by extraneous visual information any more than in healthy controls...

..Abnormalities have been reported in anterior regions with less evidence of changes in posterior regions. Methamphetamine abusers have also shown deficits on attention tests that measure response conflict and cognitive control...

Attentional control and brain metabolite levels in methamphetamine abusers

..4 years; p < .05). Positive symptom ratings were also significantly higher in the inpatients. The finding of reduced NP in the state hospital patients appears to be related to severity of symptomatology and chronicity of illness...

..The study of sequential inhibitory processes and their response to neuroleptic treatment could be important methods for understanding the temporal parameters associated with inhibition in schizophrenia...

Association of estrogen levels with neuropsychological performance in women with schizophrenia

..In addition, FMT uptake did not differ from a group of young adult female monkeys at either time point. These findings may represent a compensatory up-regulation of aromatic L- amino acid decarboxylase (AADC) activity...

Mood-elevating effects of opioid analgesics in patients with bipolar disorder

..None of the comparison subjects reported a significant mood reaction from opioid analgesics. These results indicate that opioid analgesics can have an important mood-altering effect on patients with known bipolar disorder...
